One embodiment of the present invention provides a system for calibrating a model of a digital circuit to account for noise effects between signal lines. The system operates by first fabricating a digital circuit for calibration purposes. Next, an input signal is applied to an aggressor net within the digital circuit. The system then measures how noise from the input signal affects the amplitude of a signal on a victim net within the digital circuit. Finally, the system adjusts parameters of the circuit model using the measured results.

A single-input/dual output sense amplifier includes cross-coupled transistors connected to a reference voltage; a first input transistor and a second input transistor connected to the cross-coupled transistors, wherein the first input transistor is coupled to a single input bit-line and the second input transistor is coupled to a reference voltage; an inverter receiving the input bit-line signal and outputting a complement of the input bit-line signal; a control circuit coupled to the second input transistor and receiving the complement of the input bit-line signal, wherein the cross-coupled transistors produce dual differential outputs. A method of producing dual differential output signals from a single input signal includes receiving a single input bit-line signal; inverting the received single input bit-line signal to produce the complement of the received single input bit-line signal; controlling the charging and discharging of a reference node based on the complement of the received input bit-line signal; and outputting dual differential output signals based on the single input bit-line signal and the reference node.
